Comparison of changes in serum total cholesterol induced by chitosan and placebo treatments.
| Placebo ∆ | Chitosan ∆ | p-Value Chitosan vs. Placebo | |
|---|---|---|---|
| All subjects (mg/dL) | −5.13 ± 24.79 | −12.51 ± 28.22 *** | 0.3336 # |
| % subjects decrease | 63.0 | 67.2 | 0.6968 # |
| % subjects increase | 37.0 | 32.8 | |
| Change vs. baseline | |||
| Spearman R | −0.4792 | −0.3587 | |
| Spearman p-value | 0.0002 | 0.0045 | 0.9399 |
| Difference in slope (p-value) | 0.0002 $ | 0.0066 $ | 0.0553 & |
∆ Wilcoxon p-value expressing the significance of the change compared to zero, *** p < 0.001, # data are expressed as p-values using the Mann–Whitney test, $ value expresses whether slope is different from zero, & value expresses whether slopes under chitosan and placebo treatments are different.
